Sal is tiling his entryway. His floor plan is drawn on a unit grid. Each unit length represents one foot. Tile costs $1.05 per square foot. How much will sal pay to tile his entryway?

Step-by-step explanation:

Here, as we can see in the given figure:

The floor plan is an irregular figure.

So, we try and divide the figure in to two equal parts horizontally.

The first part : Trapezoid

The second part : Parallelogram

Now, the dimensions of the trapezoid are:

Base Length  = 7 ft

Top Length  = 4 ft

Height  = 6 ft

Area of the Trapezoid  =  

=

So, the area of trapezium  = 33  sq ft.  .......... (1)

Now, the dimensions of the parallelogram are:

Length  =  4 ft   =   Width

Area of the parallelogram  =  Length x Width

= 4 ft x 4 ft = 16 sq ft

So, the area of parallelogram = 16  sq ft.  .......... (2)

Now adding (1) and (2), we get

Total Area  of the entryway  =  33 sq ft + 16 sq ft =  49 sq ft

Cost  of tiling per sq ft   = $1.05  

So, the cost of tiling  49 sq ft  =  $1.05  x 49

= $51.45

Hence, the total amount paid by Sal to tile his entryway  = $51.45

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
